Hi Scott
Yes you need to check all your attributes being passed because they are different for the 9ks with respect to 1ks
For example
ip:ip-unnumbered=loopback 0 would need to be ipv4:ipv4-unnumbered=loopback 0
to send routes you need to use framed-route and not cisco avpair ip:route
and several others
one that took us awhile to find was needing service-type outbound-user to set up l2tp tunnels out to some of our customers.
And as Tom said if one attributes comes in that is not accepted the user will not come up.
So make sure to test well
